This is why Bernie had a relatively pro-gun record that I wish he’d been more unapologetic about when running for president. I don’t agree with it but I do think it would have been a good way of showing their was actually an issue he was more moderate and pragmatic then other Democrats on and it could have poked a hole in their electability argument.
